Abstract

The telecommunications industry plays a role in meeting the needs of digital connectivity services to the community, especially in line with the community's need for internet connections which is increasing rapidly. As one of the telecommunications service operators in Indonesia, "PT. MNO Indonesia" must meet this need to get maximum profit and the best service to the customers with the right business strategy. However, the current connectivity business model is still the mainstay, with revenue levels that tend to stagnate and even experience a decline. The provision of network services and investment in infrastructure development are still the main concerns, so a change in business strategy is needed. This study proposes several recommendations for business strategies to increase revenue based on reviewing and analyzing financial data and statistics for Indonesian and international telecommunications businesses. In this study, financial report data and digital sector statistical data were analyzed and divided into four aspects: traffic, finance, network development, and digital service with the min-max method, standard deviation, and average. From the analysis conducted in this research, "PT. MNO Indonesia" needs to transform its business into digital business model.

Abstract

Digital transformation in education improves entities by implementing significant changes in education by combining information technology, computing, communication, and coordination. This paper proposes improving education through a digital transformation through platforms, specifically online skills-based learning called ASAH Skill. The survey was conducted by collecting question data from Google Forms. By using the Problem Validation method and Primary Data, obtained Product Validation on Customer Needs (Survey) and Product Strategy (Affinity Diagram). It is a market-based validation as a guide for designing ASAH Skill products that meet the criteria and needs of Skill Providers and Seekers. The method considered consists of three steps, namely strategic situation analysis (SSA), strategy formulation (SF), and strategy implementation (SI). We have finally found what customers need to develop their skills during the isolation period of the covid-19 pandemic. The survey was conducted on 51 respondents. Strategic Implementation consists of Mockup, Business Model Canvas (BMC), and Problem Solution Fit Canvas. The biggest detention experienced by respondents was very limited mobility (82.4%). The survey also showed that most of the activities respondents did during the pandemic were exploring new things (37.3%). Video editing is the most learned skill during the pandemic (25.9%), and YouTube is the respondents' main choice as a medium for learning skills (43.1%). Overall, the results of the study show that dispensing and learning skills are a new need for society during a pandemic. The provision of a platform is a development opportunity as a forum for the dissemination and learning of skills. The highest priority is on the 'easy to use' attribute where all respondents give an importance rating of 5.

Abstract

The telecommunication sector mainly comprises operators, vendors, and regulators. In Indonesia, tele- communications operator companies tend to decrease profits from the first quarter of 2017 to the third quarter of 2018. This condition is due to the tight competition of telecommunication service providers, high operational costs, and digital transformation that does not provide substantial revenue for the company. Telecommunica- tions operators need other service options that can expand target market segmentation. It aims to open up a new blue ocean as a new source of income. The world is getting closer to massive communication technology, so high-speed communication is needed. Therefore, telecommunications operators can open new service options based on the visible light spectrum as their communication resources. This option can be integrated with ambient lighting, a wide spectrum ranging from radio waves, and greater bandwidth, making visible light suitable for IoT- 5G services. This research aims to design a wireless visible light communication business model. Several frame- works are used, such as the magic triangle of St. Gallen, Osterwalder Business Model Canvas, and PESTLE analysis. The business model design results in a business model with B2B market segmentation being the main focus and B2C market segmentation to acquire retail customers.

Abstract

Customer churn frequently occurs in the telecommunications industry, which provides services and can be detrimental to companies. A predictive model can be useful in determining and analyzing the causes of churn actions taken by customers. This paper aims to analyze and implement machine learning models to predict churn actions using Kaggle data on customer churn. The models considered for this research include the XG Boost Classifier algorithm, Bernoulli Naïve Bayes, and Decision Tree algorithms. The research covers the steps of data preparation, cleaning, and transformation, exploratory data analysis (EDA), prediction model design, and analysis of accuracy, F1 Score, receiver operating characteristic (ROC) curve, and area under the ROC curve (AUC) score. The EDA results indicate that the contract type, length of tenure, monthly invoice, and total bill are the most influential features affecting churn actions. Among the models considered, the XG Boost Classifier algorithm achieved the highest accuracy and F1 score of 81.59% and 74.76%, respectively. However, in terms of efficiency, the Bernoulli Naïve Bayes and Decision Tree algorithms outperformed XG Boost, with AUC scores of 0.7469 and 0.7468, respectively.

Abstract

Penggunaan teknologi pada ranah kesehatan berkembang pesat, salah satunya yang cukup popular adalah Wireless Body Area Network (WBAN). WBAN merupakan teknologi yang menawarkan akses informasi pada tubuh dan perangkat kesehatan secara nirkabel. Sakah satu perangkat untuk mendukung teknologi nirkabel adalah antena. Penelitian ini fokus pada perancangan antena yang digunakan pada aplikasi WBAN. Antena dirancang menggunakan metode coplanar waveguide (CPW) dan matching stub. Metode ini berguna untuk mencapai bandwidth yang sangat lebar (ultra wideband) dan dapat melakukan tuning pada frekuensi kerja yang akan dicapai. Hasil simulasi menunjukan antena mempunyai bandwidth  sebesar 17,8 GHz pada rentang frekuensi 2, 953 GHz – 20,761 GHz dan gain maksimal 6,09 dBi. Simulasi antena juga dilakukan dengan menempatkan antena di atas material tekstil seperti jeans dan katun. Posisi antena di atas jeans mempunyai peningkatan gain simulasi sebesar 9,85% dan lebar bandwidth bertambah 1 GHZ dibanding hasil tanpa material. Sedangkan dengan material katun, nilai bandwidth juga bertambah namun gain simulasi mengalami seidkit penurunan. Walaupun demikian, dengan adanya kedua material tekstil tersebut tidak mempengaruhi performa antena karena masih berada pada frekuensi resonan WBAN yaitu 3,1 GHz – 10.6 GHz. Dengan demikian perancangan antena ini telah sesuai dengan spesifikasi WBAN pada frekuensi ultra wideband dan metode CPW dan stub telah mencapai hasil sesuai dengan tujuan.

Abstract

This research develops a 64-element microstrip antenna array design using the Dolph-Chebyshev method for capturing Himawari-8 satellite data. Proximitycoupled feed is employed to enhance efficiency and minimize unwanted radiation. Dolph-Chebyshev amplitude distribution is implemented through Wilkinson unequal power dividers and λ/4 transformers for optimizing beamwidth and sidelobe levels. Simulation results show the antenna operates in the frequency range of 4.1036-4.459 GHz with a gain of 23.46 dB at 4.148 GHz. The directional radiation pattern has a 3 dB beamwidth of 6.5° in the E-Plane and 4.9° in the HPlane, with main lobe directions of 0° and 1° respectively. The total antenna dimensions of 752 mm × 627.94 mm × 3.255 mm without requiring a parabolic reflector make it more compact compared to previous designs.
